FLAT-IRON' HEATER.

Specication of Letters Patent.

Patented May 7, 191s.

Application filed I u1y 9, 1917. Serial No. 179,447.

This invention relates to stoves and furnaces, and more especially totool heaters; and the object of the same is to produce a' device of thiskind which burns coal orL other hard fuel, and is intended for heatingflat irons,` although it may be used for cooking or other heatingpurposes.

The invention consists in the details hereinafter more fully describedand claimed, and as shown in thedrawings wherein Figure 1 is a frontelevation of this heater complete, one end of the door being broken awayto show the interior construction.

Fig. 2 is a plan view with one endof the cover broken away,

Fig. 3 is an end elevation with the ash pan drawn out and laid aside.

Fig. 4 is a central vertical longitudinal section.

Fig. 5 is a central vertical transverse section looking toward thefastening device for the fire pot.

Fig. 6 is a perspective detail of the re pot removed.

Fig. 7 is a inverted. A

Mounted on suitable feet 1 is a casing which in its contour andstructure comprises an ash pit 2 above which the casing is reduced inwidth t'o produce a narrow neck 3, and above the kneck the casing isagain widened to kproduce a body 4 whose side walls may-convergeslightly as shown in Fig. 3, and whose open upper end is provided withgrating y 5 Isurrounded by an upstanding detail of one reducing elementflange 6, and the latter is preferably also surrounded by an outstandingflange 7 Hinged at 8 is a cover 9 having perforations 10 in its top, andslidably mounted beneath said cover and carried by it is a damper 11havinga handle 12 projecting from one end. What might be called thefront side of the body is open, and hinged at 13 along door 14 (partlybroken away in Fig. 1) and which when raised and closed is held in thisposition by means of la button 15 engaging a keeper 16. Within the neck3 below the hinge line 13 of the door is mounted a longitudinallymovable damper 17 which may be set to regulate the size of the inlet ordraft openings 18 by means of its handle 19. Finally a bail 20v isprovided, whose extremities are connected with the ends of the casing sothat the entire device can be lifted and carried from point to point,and when not in use this bail is thrown back out of the way of themoving members or parts.

In one end of the ash pit 3 is an opening normally closed by a door 21having a suitable catch 22, and when this door is opened an ash pan 23may be slid into the pit or removed therefrom by its handle 24,

the pan being of 1such length that when it is in place ythe ash pit door21 may be closed and latched so that the controlled by the dampers.Within the ends of the body just above the neck are brackets 25 carryingnotched bearings 26 in which rest trunnions 27 projecting from oppositeends of a fire pot 28 loosely disposed within and nearly. fillingalthough purposely made slightly smaller than the interior of the samefor reasons which will appear. This lire pot underlies the grating andis open at its top beneath the same, its bottom is perforated as at 29and provided with upstanding ribs 30 in the nature of grate barsextending longitudinally between the rows of perforations as seen, andby preference the interior is lined with metal to prevent burning out.

The shaker comprises a bar 31 pivoted at its rear end to the backY ofthe neck and having a handle 32 at its front end extending through aslot 33 in the neck just above the damper 17, and between its ends thisbar passes through a fork 34 depending from the tire pot at about thecenter of its length, so that when the handle is moved to and fro withinthe slot the trunnions yof the ash pit slide in their slotted bearingsand the entire structure is reciprocated longitudidraft is entirelythebody of the casing,l

fuel to replenish that burned and pass it down into the pan in the shapeof ashes, the front door 14 is opened and the entire pot swung forwardon its trunnions as its shape and size will permit. Pivoted at 35 withinone end of the pot is a latch 36 having through its free end a pin 3'?which projects thence outward through an arcuate slot 88 in the end ofthe lire pot| and through a second arcuate slot 39 in the end wall ofthe casing, beyond which the outer end of the pin serves as a handle.rlhis last-named slot has at its rear end a depending notch 40 intowhich the handle drops when the lire potstands upright in its normalposition and is housed within the casing. lt is obvious that by raisingthe handle out of this notch and moving' it forward through the slot 39,the open upper end of the fire pot is swung forward as its body rocks onits trunnions in a manner which will be clear. The same can then becharged with fuel in the shape of coal, coke, or other granularsubstance such as is designed to form the heating agent of this device.By means of the same handle the fire pot is then restored to its properposition and the front door closed and latched, and the device is readyfor use.

F or the purpose of reducing the exposed area of the grating at timessingle flat iron is to be heate for instance, I employ a plurality ofinverted cup-shaped or more accurately, box-shaped elements 50 as bestseen in F ig. 7, each of which is of a size to t within the `flange 6 atone end of the same and to rest upon the grating, and when in place saidelement blocks out practically a quarter of the exposed surface at thetop of the heater. l purposely make these elements cup-shaped asdescribed and shown, in order that when in use their flanged sides mayrest against the flanges (3 and their flat upper faces may constituteheating surfaces for throwing off heat into thc compartment or forcooking or warming utensils or .food if desired; and yet when theseelements are both employed there is practically a half of the gratingsurface vet exposed and upon which two ordinary flat irons may be placedto receive the direct heat from the coals. From this it will beunderstood that 1 prefer to make the grating of such a size as normallyto accommodate four flat irons, but in this respect 1 do not wish to belimited.

The lire having een started in the usual manner, its burning isregulated by prop erly setting the dampers, or perhaps the cover couldbe left entirely open until the fire was well under way. After the coalsare aglow, the lower damper may be closed to check the draft, and thecover also closed and its damper also more or less closed. The devicewhen only a may now be used as a heater for an ordinary apartment, andfor warming d1shes, food, and the like. lVhen the upper damper is openedit is quite possible to cook upon the device. llhen the cover is openedso as to expose the grating, a higher degree of heat is availablebecause tools such as flat irons and other articles can be placed on thegrating and heated by direct contact of the flames from the coals. Thisis the purpose for which my invention is primarily intended, but Ireserve the right to use it in any manner possible. From time to timethe lire pot must be shaken, and the ashes fall into the ash pan; and onoccasions the latter must be removed and emptied in a manner which willbe well understood. From time.

to time also the fuel must be replenished within the lire pot ,in amanner already described. l do not wish to be limited to the shape,proportions, or materials of parts, and details are unimportantexcepting as claimed below. f
